2. Related Art
Conventional mails in the past several centuries have played an important role in communicating and expressing one's feelings and emotions (not to mention what one can put in the mail). In order to ensure privacy, various types of envelopes and bags were developed to contain such information.
As “privacy” tends to draw unwanted curiosity, in order to easily detect whether contents inside the envelope or bag has been tampered, sealing methods from ancient wax seals to today's super bond glue and tapes were developed. Still, after all these years no matter how hard people tried, simple tampering methods continue to violate privacy and leave envelopes or bags visually intact. Nowadays, in accompany with new technologies and worldwide web developments, electronic mails have become an important communication media among people. However, most consumers think that electronic mails are virtual, insubstantial and intangible, and may have safety problems during transfer. Therefore, conventional mails are still commonly used to deliver formal or important articles or items. To secure the safety and confidentiality of the mail becomes an important issue to be resolved.
It is well known that sometimes in the military, an officer can check a private mail by simply cutting a narrow slit on any side of the envelope to access the content, then gluing it back afterwards. Yet, the recipients will not notice the breakage.
Other conventional safety mails, such as express envelopes for delivering confidential documents, bank and credit card statements, credit cards or other important articles, face the same serious problem related to privacy and security.
For example, as shown in
Therefore, it is required to have a confidential envelope that clearly shows evidence after being opened.
Japan publication number 61-110547 disclosed an envelope characterized in: using a strong coating paint to print texts, graphics and symbols onto any two opposite sides of the inner film (2a), forming the envelope and sealing the envelope by this printed side. In other words, before the envelope is sealed, a layer of printed texts, graphics or symbols is painted on its “inner surface”. Since this printed layer is hidden in between the two sides of the envelope being sealed, it cannot be seem from outside when looking at the envelope. However, if the sealed area is peeled apart, the hidden printed layer will reveal and the printed texts, graphics or symbols will be separated as shown in
The object of this invention is to provide a confidential envelope/bag that clearly shows evidence when being opened so that even before opening the envelope/bag, the recipient can easily notice whether the enclosure has been tampered or not.
A confidential envelope/bag according to this invention is composed of a face and a back. The left, right and bottom sides of the face are linked respectively with the left, right and bottom sides of the back and formed with edges. A covering lid is extended from top of the face. A folding line paralleled to and spaced with a suitable distance from the top of the back is formed on the lid. The envelope/bag is sealed by folding the lid and pasting it to the surface of the back.
The edges of the face, the back, and the top folding line form a sealing zone along the edges. Along the edges and the folding line, there are sealing prints of color regions, patterns, marks, graphics, texts, numbers made of paint, coating, ink, fluorescent dye, or even concaves, or extrusions. The sealing prints surround the circumference of the face, the back and across the two so that any intentional cut made for accessing the enclosure will leave noticeable evidence on the envelope/bag. Furthermore, the intruder has to make a long cut in the sealing zone to be able to take out the enclosure and it will leave an evident slit that is hard to remove.
There is a warning sign on the back of the envelope reminding the recipient to check whether or not the sealing zone has being broken; if so, the immediate remedial actions should be taken. There can also be a transparent portion on the face of the envelope allowing a certain content of the enclosure to expose.
The invention will become more apparent from the detailed description given herein below. However, this description is for illustrations only and is not limitative of the invention, wherein:
A folding line 12 paralleled to and spaced with a suitable distance from the top of the back 20 is formed on the lid 11. The envelope/bag is sealed by folding the lid 11 and pasting it to the surface of the back 20. There is an adhesive section prepared at the back of the lid 11 so that when being folded and pasted, a top sealing zone 41 is formed by the lid 11.
Besides the bottom edge 31 forming on the bottom of the face 10 and the bottom of the back 20, there is a suitable area of bottom sealing zone 42 formed between the bottom portions of the face 10 and the back 20. Like the top sealing zone 41, the bottom sealing zone 42 is an area where periphery portions of the face 10 and the back 20 are pasted and adhered to each other.
Besides the side edges 32, 33 forming on both sides of the face 10 and the back 20, there are two suitable areas of side sealing zones 43, 44 formed between both side portions of the face 10 and the back 20. Like the top sealing zone 41, the side sealing zones 43, 44 are areas where periphery portions of the face 10 and the back 20 are pasted and adhered to each other.
Also referring to
Similarly, there is a sealing print 52 of color regions, patterns, marks, graphics, texts, numbers made of paint, coating, ink, fluorescent dye, or even concaves, or extrusions form on bottom portions of the face 10 and the back 20, and across the bottom edge 31 so that any intentional cut on the bottom portion will leave noticeable evidence on the envelope/bag. More specifically, the sealing print 52 is formed on the bottom outermost periphery portion of the outer surfaces of the face 10 and the back 20. The bottom portion abuts the bottom edge 31. The sealing print 51 crosses the bottom edge 31 so as to extend from the face 10 to the back 20 without discontinuity.
Also, there are two sealing prints 53, 54 of color regions, patterns, marks, graphics, texts, numbers made of paint, coating, ink, fluorescent dye, or even concaves, or extrusions form on two side portions of the face 10 and the back 20, and across the side edges 32, 33. Thus, any intentional cut for taking out the enclosure on any side portion will leave noticeable evidence on the envelope/bag. More specifically, the sealing prints 53, 54 are formed on two side outermost periphery portions of the outer surfaces of the face 10 and the back 20. The two side portions respectively abut the side edges 32, 33. The sealing prints 53, 54 respectively cross the side edges 32, 33 so as to extend from the face 10 to the back 20 without discontinuity.
Therefore, the circumference of the confidential envelope/bag is furnished with sealing zones 41, 42, 43, 44 and sealing prints 51, 52, 53, 54 after the envelope being sealed. Any intruder who intentionally cuts the envelope at any sealing zone 41, 42, 43 or 44 for taking out the enclosure will damage the sealing print 51, 52, 53 or 54. Because the sealing prints 51, 52, 53, 54 are color regions, patterns, marks, graphics, texts, numbers made of paint, coating, ink, fluorescent dye, or even concaves, or extrusions that cross the edges 12, 31, 32 and 33, any cutting or re-sealing is apparently noticeable due to the inconsistency of the sealing prints. Nevertheless, due to the surrounding sealing zones 41, 42, 43 and 44, the cut has to be wide enough for getting the enclosure and it is hard to recover or re-seal.
The concaves or extrusions on the sealing prints 51, 52, 53, 54 are for the blinds to check if the sealing prints are consistent. The printing materials for the sealing prints 51, 52, 53, 54 are selected according to different needs. For example, some kinds of invisible ink are used for military-purpose sealing printings that can only be seen through a specific machine. Thus, an intruder leaves noticeable breakage evidence easily without even aware it.
A notice portion 21 can be arranged at the back 20 for writing or printing warning notice to remind the recipient to check if any of the sealing zones 51, 52, 53 and 54 is being broken or missing.
There can also be a window 13 with transparent film on the face 10 to expose a certain content or information of the enclosure for informing the deliverer or recipient.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
